Old Lyme, CT â€“ April 17, 2012 â€“Â Building a hi-fi device that sounds so brilliant, so crystal clear and so free of distortion as if one were sitting right in front of the audio source. Creating a level of acoustics that surpasses everything that has gone before. These are the visions that driveÂ SennheiserÂ in the development of its high-end products. For the first time, Sennheiser is now launching an amplifier for dynamic headphones, thus making the Sennheiser sound experience perfect. The digital HDVD 800 has a fully symmetrical layout and sampling frequencies of up to 24bit/192kHz to ensure an unequalled listening experience. It also harmonises perfectly with Sennheiser’s HDÂ 800, HDÂ 700, HDÂ 650 and HDÂ 600 high-end headphones.
The outstanding features of the HDVDÂ 800 include its balanced sound image, maximum precision and impressive spatiality. The high-end headphone amplifier has a fully symmetrical layout for operation with analogue audio sources, thus ensuring absolutely symmetrical signal transmission from the source to the headphones. For use with digital sources, the amplifier is equipped with a high-quality Burr-Brown digital/analogue converter that converts digital audio data into analogue signals with a resolution of 24 bits and a sampling rate of up to 192Â kHz. This enables the HDVDÂ 800 to transmit the entire frequency spectrum of high-end audio sources without any loss of frequencies.

Top-quality technology, top-quality sound
Signal processing in the HDVDÂ 800 is fully symmetrical. That means that not only the signal input into the amplifier is symmetrical but also the signal output and therefore the connection to the headphones. â€œThe fully symmetrical principle effectively compensates for interference and distortion. The sound therefore becomes much clearer as total harmonic distortion is minimised,” explained Axel Grell, Sennheiserâ€™s Senior Acoustical Engineer.Sennheiser supplies specially made cables for the symmetrical connection to headphones. The headphones can, however, also be connected using a normal 6.3 mm jack plug. In addition to the symmetrical inputs, the HDVDÂ 800 also has an asymmetrical input socket; incoming signals are symmetrised before further processing takes place. Digital sources are connected to the rear of the unit as an AES/EBU input, S/PDIF(optical and coaxial) or USB. The USB 2.0 audio standard offers 24 bit data transmission at 192 KHz.*

In order to fully exploit the sound potential of the HDVDÂ 800 with any audio source, a rotary gain switch at the rear of the unit provides simple adaptation of the amplifier output to the audio input voltage. This ensures that the dynamic range can be used to its full extent.

And such meticulous attention has also been applied to the exterior. Both the housing and the potentiometer control as well as the rotary switch for selecting the source are made of anodised aluminium, while the front panel of the housing and the controls are milled from solid material. The HDVD was developed and designed in Germany, and the latest member of Sennheiserâ€™s high-end series is also being manufactured there.

The new digital HDVDÂ 800 will be delivered to Sennheiserâ€™s worldwide sales partners from September.
